Abstract: An implantable sensor assembly for use during spinal fusion. The implantable sensor assembly can include a component of an implantable prosthesis and an implantable cartridge associated with the component. The implantable cartridge can include at least one sensor capable of detecting one or more kinematic measurements associated with a patient and generating sensor data, and an antenna in electrical communication with at least one sensor, wherein the antenna transmits sensor data to a receiver at a remote location.

Abstract: Systems and methods are provided for accurately measuring and allocating treated oil. Separators can be modified to include automatic control systems utilizing active flow controls and level sensors. The automatic control systems can be configured to cause oil to flow at a rate and with a duration sufficient to accurately measure the amount of oil transferred from the separator. The systems and methods also provide for a method of correcting for oil density variations. The systems and methods also allow for fail-safe operations by having the active flow controls fail in an open position allowing pre-existing passive flow control valves to operate normally.
